This trial uses brain scans to understand why people with long COVID feel very tired or have trouble thinking clearly. It could help find new treatments for these symptoms.
Baltimore, MarylandAges 18–75 - NCT07271225Recruiting
Ear acupuncture for nausea from TB drugs
This study tests whether ear acupuncture can help reduce nausea and vomiting caused by tuberculosis medications. It is for people who are at least 17 years old, have drug-sensitive or certain types of drug-resistant TB, and feel sick after taking their TB pills.
Jakarta, Jakarta TimurAges 17 years+ - NCT07275333Recruiting
HPV self-sampling for cervical screening in Ukraine
This trial tests if women can collect their own samples at home to check for HPV, a virus that can cause cervical cancer. It aims to make screening easier during the war in Ukraine.
ZaporizhzhyaAges 30–60 - NCT07273526Recruiting
Adrenaline vs. Dopamine for septic shock in children
This study compares two medicines, adrenaline and dopamine, to see which works better for children with septic shock (a serious infection causing very low blood pressure) that does not improve with fluids.
Faisalābad, Punjab ProvinceAges 1 month–1 year - NCT07275307Recruiting
Test of a wound gel to prevent infections after heart surgery
This study tests whether a special gel applied to the chest incision during heart surgery can lower the chance of wound infections. The gel may help keep the incision site clean and help it heal better.
San Donato Milanese, MichiganAges 18 years+ - NCT07274046Recruiting
Tick-borne encephalitis study in the Czech Republic
This study looks at the cost and effectiveness of the tick-borne encephalitis vaccine. It will also track the recovery of patients hospitalized with confirmed tick-borne encephalitis to understand the long-term impact of the disease.
Ostrava, Moravian-Silesian RegionAges Any age - NCT07275827RecruitingPhase 3
Testing 3 treatments for H. pylori infection
This study compares two different acid-reducing medications, given with or without zinc, to see which is safer and works best for treating H. pylori. All treatments are combined with two antibiotics.
Shibīn al KawmAges 19 years+ - NCT07278700Recruiting
Fever and respiratory infection study
This study looks at adults with a fever caused by a respiratory infection. If you qualify, you will have a blood draw as part of your regular care, and researchers will use it to learn more about your condition.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT07277387Recruiting
Predicting complications in high-risk fever with low white blood cells
This trial studies whether proteins in your blood can predict complications when you have a fever and very low white blood cells after cancer treatment. It aims to help doctors choose the best antibiotics early on.
Barcelona, BarcelonaAges 18 years+ - NCT07278206Recruiting
Brain stimulation for long COVID fatigue and brain fog
This trial tests whether a non-invasive brain treatment called rTMS (repetitive transcranial magnetic stimulation) can help with the severe fatigue and brain fog that often come with long COVID. You would need to be able to come to the hospital for multiple treatment sessions.
AmsterdamAges 18 years+ - NCT07269314Recruiting
Comparing PCR tests to standard methods for infections
This trial uses stored samples to see if a newer test (PCR) is as good as standard tests at detecting three infections: Pneumocystis (a lung infection), malaria, and leishmaniasis. It does not involve new treatments.
Pavia, LombardyAges Any age - NCT07275554Recruiting
Gene patterns and risk prediction in hepatitis B liver failure
This study looks at how gene changes (methylation) in people with hepatitis B-related liver failure may predict how well they will do. It aims to create a risk score to guide treatment.
Jinan, ShandongAges 18 years+ - NCT07272122RecruitingPhase 3
Reducing flies to lower illness in camps
